SolarWise Intelligent Sub Array Box

SolarWise SUB Array Box/Combiners integrate multi-array boxes into a Centralized DC power system for connection to the centralized inverters up to 500kW

SolarWise SUB Array Boxes work at the upper level of combining power from array boxes into even bigger power before feeding off to the inverter.

SUB Array Boxes or Combiner Boxes are electrical enclosures of simple functions that combine large currents from array boxes into much larger currents up to 1200A before going into centralized inverters.
Enerwise offers SUB Array Boxes that combines 4 to 16 strings from Array Boxes. Each SUB Array Box input can range from 50A to 250A in size.
We offer complete Standing Types of higher rating or Hanged Types that are of smaller rating.

Solar SUB String monitoring SWF820 can be optionally installed to measure currents to detect abnormal current levels, leakage current warnings and detect power of the string before going into the inverter.

Controls by SWF820 can be done by tripping each MCCB via a tripping function issued by the SCADA or via SolarWise WEB controls. Isolation of a string inside a SUB Array Box provides safety in case of an error in an array occurs.
